Think you'll find he died Dec.1853 Gloucester (registration district for Brockworth).
There seems to be anomalies with the recording of this - on FreeBMD regn. district just has a star (underlined) with ref. 6a 131, FindMyPast have district as Gloucester ref. 6a 151, and Ancestry have no district at all, ref. 6a 131. However, if you look at the original GRO index you will see that for district it's written as 'Gla'ster' which has no doubt caused all the confusion! I personally think that the page no. is 151 (as on FindMyPast).
